A new method for combating prostate cancer was developed by researchers of Hebrew university.
The student, Danny Goldstein, received the Barenholz Prize for Creativity and Originality in Applied Research for his work. The award, named for its donor, Yehezkel Barenholz, the Dr. Daniel G. Miller Professor of Cancer Research at the Hebrew University-Hadassah Medical School, was presented recently during the 70th meeting of the Hebrew Universitys Board of Governors.
Prostate cancer is the second leading cause of cancer-related death for men in the U.S. Present treatments for metastatic prostate cancer (cancer cells that spread to other parts of the body) include hormonal therapy, chemotherapy and radiotherapy, which frequently have serious side effects.
The well known drug, paclitaxel, exhibits a wide spectrum of anti-tumor activity. However, its therapeutic application in cancer therapy is limited, in part, due to its low water solubility, making it difficult to effectively deliver the drug to the points needed. It is also known to induce hypersensitivity reactions.
Therefore, novel methods are needed that would allow for delivery of effective concentrations of paclitaxel over extended time intervals while minimizing toxicity.
Targeting drugs to disseminated prostate metastases is one of the most challenging goals in prostate cancer therapy. Drug carriers -- nanoemulsions, liposomes (fatty droplets) and nanoparticles -- have shown great potential as delivery systems for an increasing number of active molecules.
Although capable of enhanced accumulation in the target tissue, these carriers cannot achieve their missions unless specific binding agents are attached to them which will ensure that they succeed in attaching to the targeted tissues.
It has been shown that the HER2 receptor is over-expressed in prostate cancer cells. It was also known that trastuzumab (an antibodyPage: 1 2 Related medicine news :1
